You are allowing Satan to get you hung up on insignificant matters. What is "Trinity"? Lets dissect the word.
Trinity is made up of first of all "Tri", meaning 3. The bible clearly speaks of the Father, Son and Holy Spirit. Is that 3? Should we invent another convenient word to describe the Father, Son and Holy Spirit? Or, when we speak of the three persons of God, should we always say: "Father, Son and Holy Spirit"?
Why not rather say Trinity, meaning the 3 persons of God. Do you deny the 3 persons of God?
There are a number of people that get hung up on the word "Trinity" but it generally is because they want to avoid the truth. They want to avoid the work of God in their hearts. After all, if you are too confused...deliberately...to understand the doctrine of salvation, you won't feel any guilt about rejecting it.
God will not accept any excuses. The ignorant, as well as those who reject the truth, will be condemned to Hell equally. Ignorance is no excuse. An ignorant person will have no success in telling God they didn't know.
